It doesn't feel right that lightning strikes can transform dinitrogen into nitrates and ammoniates that fertilize soil. It feels like an excuse the druid in the party used to justify their druidness after someone pointed out they only cast lightning spells.

It’s always 20 years that they claim to have been doing this, and they always think that’s somehow impressive, but all I ever hear is that they started a hobby and never bothered to do a single bit of research on it in two decades.

My favorite is when they claim that a full water change will kill the cycle but that the cycle also lives on every surface. A full water change will alter your PH, GH, KH, and TDS, all of which can harm or kill your fish and inverts if you don’t acclimate them to it, but unless you’re leaving your filter off/out of water for an extended period and/or putting untreated water back into the tank, it’s not going to kill your cycle. They’re also correct that the bacteria lives on every surface, but the MAJORITY lives in your filter, where the most oxygen is at, which is why you can set-up a brand new tank with an established filter and have a fully cycled tank.

Nitrogen is the most abundant element in our planet’s atmosphere. Approximately 78% of the atmosphere is made up of nitrogen gas (N2).
Nitrogen is a crucially important component for all life. It is an important part of many cells and processes such as amino acids, proteins and even our DNA. It is also needed to make chlorophyll in plants, which is used in photosynthesis to make their food.
As part of these life processes, nitrogen is transformed from one chemical form to another. The transformations that nitrogen undergoes as it moves between the atmosphere, the land and living things make up the nitrogen cycle.

Despacita’s babies are all walking on the surface tension!
I stayed at a friend’s place over the weekend and came back to a snail and duckweed explosion. Here in these two pics I’ve cleaned it up but it had completely eclipsed the surface of the tank and all the baby snails were tarzanning about on the roots. I wish I took a picture now but the amount had filled up an entire breakfast bowl. I’m sure it will happen again cause duckweed is always super prolific.
I’ve lassoed all that could fit into a loop of airline tubing and tucked them into the corner. I use a bit of fishing line and a plant weight to anchor it down. They’ll break free and spill over eventually but I like how tidy it looks for now and the snails can still chill on them.
Floating plants are actually very helpful in reducing nitrates so I’m happy to see them grow. I’ve got a wider leaf variety recently: Red root floaters (Phyllanthus fluitans). They don’t have their red roots just yet but the critters love hanging out on them like mini lilly pads.

Re: your tags, PLEASE tell me about soil microbes. I only know them as funky l’il guys who break down dead matter and some of them can make you sick.
I would be happy to talk about soil microbes! They ARE funky little guys who break down dead stuff, or at least some of them are, and they're basically the foundation of nutrient cycling. Which gets very complicated very quickly, because there are ALL KINDS of nutrients and ALL KINDS of microbes that deal with them. I mostly know about carbon cycling, and a bit about nitrogen cycling, because that's why I and my coworkers study.
You've got microbes that take atmospheric nitrogen and turn it into stuff plants can use (nitrogen fixation, these include the critters that live in legume roots), and then you've got several other kinds of microbes that shuffle nitrogen from one form to another (nitrifiers, denitrifiers, probably others I'm not aware of). Carbon cycling involves SO MANY TYPES OF MICROBES, it's ridiculous, but my favorites are the methanogens - the ones that make methane. There are also methanotrophs, the ones that eat methane.
And all these little creatures have specific soil conditions that they need in order to do their jobs - methanogens like environments without oxygen, for example (that's not their only requirement though. These dudes are COMPLICATED and they have a whole list of chemicals that have to be absent in order for methane production to happen. Basically, the reaction by which methane is produced is one way to break down organic matter, but it's STUPIDLY INEFFICIENT so the methanogens get outcompeted by the more efficient microbes unless those other guys just don't have the materials they need to do their more efficient chemical reactions. These necessary chemicals are called Terminal Electron Acceptors and include stuff like iron, nitrates, nitrites, sulfates, etc.).

Biological nitrogen fixation accounts for most of the conversion of atmospheric N2 into ammonium, and thus serves as the key entry point of molecular nitrogen into the biogeochemical cycle of nitrogen (see Figure 13.1).

You smell like the idea that the trees can taste the ocean through the corpses of salmon: a green smell. Like dill and salt and rock-copper, like juniper and cedar with a bit of um. the fancy whale-vomit thing. I don’t remember the name. You smell like mist and a leaving boat a a very bright sky blue and unripe March manzanitas. Not a sharp smell but very clear and vivid
ambergris: only the very fanciest of whale vomit.

Can I ask why the nitrogen cycle is your beloathed? Like is it just the vibes
because I can't fucking memorize it to save my life I had to memorize it for multiple classes and I just couldn't. I hate it!!
